Hotter temps = lower voltage for same current (this is linear). Higher current = higher voltage, but it is non-linear. Doubling the base current will only make the base voltage slightly higher. | |

| Dec 1, 2020 at 1:42 | comment | added | TimWescott | Voting to close on the grounds that this needs more clarity. Specifically, you need to ask just one question at a time -- you're asking a whole bunch of unrelated questions, and your later questions are based on erroneous assumptions about the answers to the earlier questions. Why don't you edit your question to stop at the first question mark. We'll answer that, then you can post the next one, we'll work through that, etc. | |
| Dec 1, 2020 at 1:22 | comment | added | Sredni Vashtar | "The voltage drop between collector and emitter is a fixed value for the transistor made of certain material (0.7V for silicon and 0.2V for germanium)" No, it is not fixed and those are the (conventional) values for Vbe. Also, that diagram is misleading to say the least. The operating point of the transistor is constrained to be on the intersection of the load line with one of the output curves. It will not fall in the shaded areas. | |
